FIGS. 3A, B, and C illustrate perspective views of a camera controller100, according to one embodiment. The camera controller 100 includes ahousing 300, one or more drain mechanisms 305 a and 305 b (referred toindividually as “drain mechanism 305” hereinafter), a charging port 310,and a data port 315. The housing 300 is configured to enclose internalcomponents of the camera controller 100. In the embodiment of FIGS.3A-C, the housing 300 is substantially square-shaped with roundedcorners and edges. In some embodiments, the shape of the housing 300 mayvary to resemble other regular or irregular shapes. In the embodimentsof FIGS. 3A-C, the housing 300 is designed to have a small form factor,such that the camera controller 100 can be worn by or secured to a user.In some embodiments, the camera controller 100 is configured toremoveably mount to a mounting enclosure secured to a wrist strap orconfigured to clip onto an object, and may have dimensions similar tothose of a face of a watch. The mounting enclosure may secureablyenclose the sides and rounded edges of the housing 300, thereby securingthe camera controller 100. The housing 300 may be composed of rigidmaterials (e.g., metal, plastic, etc.) or semi-rigid materials (e.g.,rubber, soft plastic, etc.).

The housing 300 has a top surface 320 that includes one or moremicrophone ports 325, a recess 330, a central face 335, and an outerface 340. The microphone ports 325 are openings configured to allowaudio signals to enter the microphone ports for capture by microphonesembedded within the camera controller 100. In the embodiments of FIGS.3A-C, the camera controller 100 has two microphone ports 325 a and 325b, each located at opposite corners of the top surface 320. Thisconfiguration allows the camera controller 100 to capture audio signalsfrom multiple angles. Some embodiments may have only one microphone portor may have more than two microphone ports, wherein each microphone portcorresponds to a different microphone within the housing. The microphoneports 325 are positioned within the recess 330, which runs around aperimeter of the top surface 320, separating the central face 335 fromthe outer face 340 of the top surface. The central face 335 includes aslight camber such that the central face is elevated in the center andslopes downwards towards the recess 330. The outer face 340 of the topsurface 320 surrounds the recess 330 and slopes downwards towards therecess. The recess 330 is configured to channel and direct fluids awayfrom the one or more microphone ports 325, via capillary forces. Theshape and orientation of the various portions of the top surface 320prevent fluids from collecting on the top surface of the cameracontroller 100 during certain outdoor and sports activities in which thecamera controller may encounter fluids (e.g., water during aquaticsports or activities).

The drain mechanisms 305 are designed to drain fluid away from the oneor more microphone ports 325 on the top surface 320. Each drainmechanism 305 includes a drain opening 345. In the embodiments of FIGS.3A-C, the drain opening 345 is an opening on a side surface 350 of thehousing 300. A drain mechanism 305 is positioned such that fluid thatenters a microphone port 325, despite the recess 330, exits out of thedrain opening 345. The drain mechanism 305 will be discussed in furtherdetail with regards to FIG. 4.

The camera controller 100 further includes the charging port 310 and thedata port 315. The charging port 310 is configured to charge a powersource within the camera controller 100. In the embodiments of FIGS.3A-C, the charging port 310 is located on the side surface 350, but theposition may vary. In some embodiments, the charging port 310 may bewater-resistant or may include a removeable cover that has awater-resistant seal when covering the charging port. The data port 315is configured to transfer data from the camera controller 100 to anexternal data store, to allow a user to transfer data to the cameracontroller 100 (for instance, in order to configure the cameracontroller), or to enable any other suitable I/O functionalities. Thedata port 315 also includes a removeable cover that has awater-resistant seal when covering the data port.

FIG. 4 illustrates a cross-sectional view of a camera controller 100,according to one embodiment. The housing 300 includes a sound channel400, a microphone 405, a ring enclosure 410, and a membrane 415, eachconfigured to enable the camera controller 100 to capture voice commandsspoken or otherwise communicated by a user. In the embodiment of FIG. 4,the camera controller 100 includes two microphone ports 325 a and 325 b,each corresponding to a different microphone. The sound channel 400 is achannel or opening that extends from the microphone port 325 to themicrophone 405. The sound channel 400 is configured to enable thepassage of audio signals from the microphone port 325, through the soundchannel, and to the microphone 405 for capture by the microphone 405.The microphone 405 is secured within a ring enclosure 410 that at leastpartially encompasses the microphone. A membrane 415 is coupled to thering enclosure and over the microphone such that the ring enclosure andmembrane collectively create a waterproof seal over the microphone. Themembrane 415 is further configured to allow audio signals to passthrough the membrane for capture by the microphone 405, thus enablingthe microphone to detect voice commands from a user while preventingwater or other fluids from damaging the microphone.

The drain mechanism 305 helps to prevent fluid from collecting on oradjacent to the membrane 415. The drain mechanism 305 includes a drainchannel 420 that extends from the sound channel 400 to the drain opening345. In the embodiment of FIG. 4, the drain opening 345 is located onthe side surface 350, but in some embodiments it may be located on abottom surface of the housing 300. The drain channel 420 extends fromthe sound channel 400 to shunt fluid that otherwise may collect on oradjacent to the membrane 415 or plug the microphone port 325 or soundchannel 400 away from these areas and out of the camera controller 100.Such fluids might otherwise block the pathway for audio signals totravel to the microphone 405.

The drain channel 420 is configured to create a pathway between themicrophone port 325 and the drain opening 345 such that fluid enteringthe microphone port 325 can flow from the sound channel 400 through thedrain channel 420 and out the drain opening 345. In the embodiment ofFIG. 4, the sound channel 400 and the drain channel 420 angle downwardsaway from the top surface 320 of the camera controller and towards aside or bottom of the camera controller such that fluid can flow easilyfrom the microphone port 325 away from the microphone 405 and to thedrain opening 345. The housing 300 may also include one or morestructures, such as a gasket 425 around the perimeter of an insidesurface of the housing and between the drain channel 420 and a portionof the camera controller body to prevent fluid from entering variousparts of the housing from the drain mechanism 305.

The configurations described herein beneficially allow the cameracontroller 100 to operate in outdoor and sports environments in whichthe camera controller may encounter fluids by allowing fluids to drainaway from microphones. It should also be noted that while the drainmechanisms 305 described herein are used to enable fluid to drain awayfrom microphones, in practice similar drain mechanisms can be used todrain fluid away from any electrical or mechanical component.
